What 258 owners told NHTSA about the 2025 Toyota Sienna

This is a follow-up complaint regarding my new 2025 Toyota Sienna Hybrid. I am reporting a structural defect involving the vehicle floor and weld area. The issue is visible and affects the alignment and integrity of the floor structure. The vehicle was inspected by an authorized Toyota dealer. The dealer declined to repair the defect and stated that the condition is “within factory specifications,” without providing any engineering documentation or safety justification. Due to the location of the defect (floor / weld / body structure), I have serious concerns regarding occupant safety and crash performance, especially in the event of a collision. This is a brand-new vehicle, and no accident or misuse has occurred. Toyota Motor Sales has not provided a satisfactory response or resolution. I am requesting that NHTSA review this issue as a potential manufacturing and structural safety concern.

Recall is not being addressed in a timely manner

NHTSA ODI 11714554

We received notice of our 2025 Toyota Sienna second-row seat rails suspect welds in early December via mailed letter from Toyota. The recall notice was posted on Toyota's website on October 7, 2025. We called our dealership on December 13, 2025 and received no information other than the remedy was not available. It is now the end of January and as far as we can find there is no remedy. Toyota explained that our second-row seats are mounted on seat rails that may have been improperly welded. They "recommend no one sit in or use a child restraint in the second-row seats while the vehicle is moving until the remedy is performed on the vehicle." This impacts our ability to use our car fully. We purchased this vehicle for its capacity and can't take full advantage of this perk.

My 2025 Toyota Sienna Limited is subject to NHTSA Safety Recall25V668 (Toyota Recall No. 25TA12 (Interim Notice 25TB12)) regarding improperly welded second-row seat rails. The recall notice, which was mailed on 11/21/2025 and received by me the first week of December, 2025, states that these welds may fail in a high-speed collision, preventing the seats from restraining occupants and increasing the risk of serious injury. Toyota interim safety instructions advise that second-row seats should not be occupied until repaired. Prior to receiving this notice in the mail from Toyota I was unaware of the defect. There were no service lights or notifications in the car's electronic panel. I have since learned that the notice was issued on 10/7/2025. My vehicle has been grounded at Conicelli Toyota Service Department in Conshohocken, PA since 12/22/2025 - It has been inspected for this defect and to date the service department manager does not have the parts to repair it and cannot give me an expected date for the part to be available and repairs performed. I purchased this vehicle in full on 3/6/2025. Since the recall was issued on 10/7/2025, I have contacted my Toyota dealer several times to inquire on an estimated date for repair of this safety issue. I have also filed a complaint /report with Toyota Brand Engagement Center. As of 1/29/2026, Toyota has failed to provide a definitive date for the repair or a timeline for the availability of replacement parts. I purchased this vehicle to safely transport my four grandchildren -ages, [XXX] , [XXX] , [XXX] and [XXX] to and from school/daycare every day. Because I cannot safely use the second-row seats, the vehicle is unusable for its primary purpose of transporting my family. The vehicle has been effectively "out of service" for safety reasons for more than 90 cumulative days. I am asking a manufacturer buyback as the safety defect has not been remedied within a reasonable timeframe.

NHTSA Recall No. 25V668 with report date 10/7/25 provided notice that 2nd row seats were deemed unsafe to use by Toyota. We bought this vehicle specifically to be able to use the 2nd and 3rd row seats for our family. Over 3 months later, Toyota still has not provided any update on when remedy will be available for this safety recall. When will they have the remedy available?

We were notified of a safety recall in mid December but they officially released the recall in early October. I have contacted Toyota multiple times with no update. Our dealer has not been able to provide a car with the same amount of seats as our Toyota Sienna. We have been limited to a 5 seat vehicle when we purchased a 7 row seat vehicle.

Open recall with no anticipated date of being fixed. The second row seats are unsafe for passengers which makes the vehicle unusable for a family.

I am filing a complaint regarding a safety recall on my 2025 Toyota Sienna. My vehicle is subject to an active safety recall that affects the second-row seating area. Due to this recall, the second row cannot be safely used. This makes the vehicle unsuitable for normal family use. I have a family of six, and the vehicle was purchased specifically for family transportation. Despite repeated attempts, the dealer has been unable to provide a timely repair appointment. I have been informed that the proposed recall repair may involve cutting and welding the vehicle floor, which would constitute a major structural modification to a brand-new vehicle. I am extremely concerned that such a repair would negatively impact the safety, integrity, and value of the vehicle. At this time, the vehicle remains unrepaired, and I am effectively deprived of full and safe use of the car due to a safety-related defect. I am requesting that this issue be reviewed, as the recall remedy is delayed and the proposed repair raises serious safety and quality concerns. Thank you for your attention to this matter.

Toyota issued a recall on some 2025 Toyota Sienna’s. Our app notified us in October and we immediately took it to the dealership for a rental, as we were advised not to use the second row seats. We have to use those because we have 3 kids in car seats. The interim notice was not even mailed out until December. We were told they would start rolling out the fix for this issue in late December or January. It is now January, and there is no update on the recall and nobody can get any information from Toyota. Our car has been sitting for over three months at the dealership, undrivable. They are not offering any compensation for people affected by this recall. Since it has been out of service for that long, it should should be a lemon law qualification. We did not purchase a brand new car for it to sit there unusable. There does not seem to be any urgency on Toyota‘s part for this to be fixed. We have no updates or information and this does not seem to be a priority for them. There are 55,000 vehicles affected. This is a large number of people, and somebody needs to put some real pressure on Toyota to fix the problem. This is unacceptable and somebody needs to look into this further. Please pass this along and do something about it because this is not fair to those of us who in good faith are making our payments every month on a car that we are not able to use. It’s basically sitting there rotting while Toyota takes their sweet time to figure out how to fix it. I am extremely unhappy and am looking for some type of recourse. And I know I am not the only one as I am seeing posts about it on online daily, from unhappy customers. This recall is due to a safety issue, if it’s so unsafe, why aren’t they fixing it?

In October, 2025 I learned of a serious safety recall for improperly welded seat rails during manufacturing of a 2025 Toyota Sienna. I was not officially communicated of this safety recall by mail until December, 2025. I purchased this vehicle specifically to safely transport children and elderly parents, requiring full functionality of the captains seats and rear seats. While a repair/fix is being evaluated, Toyota provided the option to rent a vehicle and leave my new Toyota Sienna sitting on the dealer lot. However, no equivalent Toyota Siennas are available for long term rental at local dealerships, forcing us into highly inconvenient options for transport. Toyota was negligent in selling a new vehicle with improperly welded seat rails. There was a lapse in manufacturing quality control that is evident. Why were customers not notified until December of 2025, when these vehicles were sold nearly 6 months prior? After communications in December, 2025, there have been zero follow up correspondence from Toyota as of January 20, 2026.

They stated the second row is not safe in a high speed collision because they could eject. I’ve been using a rental for 3 months with no end insight. They stated they would have a timeline by 12/6 but that has yet to happen. My car is sitting at the dealership out in the elements for the unforeseeable future.

I received a notification on my Toyota App in mid-Oct advising there was a recall due to the second-row seat being improperly welded. At that time, I was advised a repair was in work and to avoid using those seats. However, I have four children and require all the seats in my Sienna so I have been forced to continue to use the seats, despite the warning. In December, we called our dealership to inquire if the repair was ready or if they had a loaner vehicle we could use until the repair was ready since we were not supposed to be using those seats. The answer was "no repair is ready" and there was no loaner they could provide for the foreseeable future. At this point, I feel like I am driving an unsafe car, continually forced to put my toddler and infant into seats that could become disconnected at any time because in almost 4 months Toyota still can't seem to figure out a repair for seat welds. Toyota either needs to get a repair done ASAP, provide us with a loaner, or pay for my family to rent an appropriate vehicle to support our needs until such a time as a remedy has been enacted.

I am writing regarding my 2025 Toyota Sienna, purchased in June 2025, which is currently subject to Safety Recall Interim Notice 25TB12 concerning unsafe second-row seat welds that could result in serious injury or death. I appreciate the professionalism and concern shown by Sparks Toyota in acknowledging the seriousness of this recall and providing a loaner vehicle while my Sienna is deemed unsafe to drive. However, the current loaner—a Toyota Highlander—does not meet my family’s needs and is not a reasonable substitute for the vehicle I purchased. We intentionally purchased a minivan due to our family size and lifestyle requirements. My daughter is a competitive gymnast, and we frequently travel with athletic equipment and multiple passengers. The Highlander is significantly smaller than a Sienna and cannot safely or practically accommodate our needs. Additionally, I am concerned that there is currently no repair solution or estimated completion timeline for this safety issue, leaving us indefinitely without access to a comparable vehicle. At this point, I am respectfully requesting the following: 1.Placement in a replacement vehicle comparable in size and function to a minivan (such as a Toyota Sienna or similarly sized vehicle). • If Sparks Toyota does not have an appropriate vehicle available, I request authorization for a comparable vehicle through an outside rental agency at Toyota’s expense. 2.Compensation for the ongoing inconvenience caused by the safety defect, lack of a repair timeline, and the inability to use the vehicle I purchased. 3.A clear estimate or update regarding when my vehicle is expected to be repaired and returned in a condition that is safe for my family. This recall involves a serious safety risk, and I believe it is reasonable to expect transportation that meets the same capacity and purpose as the vehicle I purchased—especially while awaiting a manufacturer-level remedy.

My name is [XXX] , and I am filing this safety complaint regarding my 2025 Toyota Sienna, VIN [XXX] , subject to Recall 25TA12. The vehicle has been under recall for a safety issue related to second-row seat rails, and I have been informed by both the dealership and Toyota representatives that they cannot guarantee the vehicle is safe for transporting children. I continue to pay full monthly finance payments (to Toyota!!! They financed my car) for this vehicle, which I cannot safely use as intended (for transporting my four children), and the dealerships in my area do not have suitable loaner vehicles. I am filing this complaint to document the ongoing safety risk and the financial and logistical burden this situation has created. I request that this recall and its handling be reviewed, and that appropriate action be taken to protect consumers. Thank you.

Recall 25TA12 for a 2025 Sienna Van second rows seats rail welds is not being handled in a timely manner by Toyota. I received a notice on Oct 5, 2025 about this recall and 90 days later there still isn’t a remedy by Toyota. This is unacceptable as Toyota put the owners on notice by saying not to use the second row seats as injuries may happen due to improperly welded seat rails. Toyota needs to step up and get this recall completed now.
